4 Claims.

This application comprises the same subject matter as in my formerapplication, Serial No.

678,650,'filed July 1, 1933; and allowed'October This invention relatesto the roofing industry and particularly to composition sheet roofing orstrip shingles such as are now being extensively used. At present suchroofing material is cut to shape and to certain standard sizes anddesigns in the factory, which necessitates the roofing con-'- tractor orretailer carrying a large stock of the different designs and colors tofit'all possible re quirements and this entails an outlay and tying upof a considerable amount of capital, with the probability of a certainpercentage of leftover material and consequent waste.

The principal object of my invention is to avoid considerable of theexpense of the present methods of merchandising such roofing byproviding a machine to cut the shingle stock to the desired length and dign from a plain roll of the material only as it is wanted; and whichis-of such simple and inexpensive naturethat it can be bought by andinstalled in the'shop of a small roofing contractor at a relativelysmall expense.

Another object is to construct the machine so that it may be easilyoperated by one man and which requires no expense for operation orupkeep.

A further object is to arrange the machine so; that the pattern ordesign cutting die can be easily changed, so that the material may becut to vari-' ous designs to suit individual purchasers without layingin a stock of material initially out to such designs as is now the case.The cost of the plain material in rolls being much less than that of thesame area of factory-cut shingles, the contractor may make his customersa more favorable price than is at present possible and still net himselfa profit, thereby of course tending to increase both the sale of thematerial and the volume of his business.

These objects I accomplish by means of such structure and relativearrangement of parts as will fully appear by a perusal of the followingspecification and claims.

In the drawings similar characters of reference indicatecorrespondingparts in the several views:

Figure l is a side elevation of the machine as in operation.

Figure 2 is a top plan view of the same.

Figure 3 is' a fragmentary enlarged cross section on the line 3-3 ofFig. 1.

Figure 4 is a plan viewof the shingles formed by a single cuttingoperation of the machine.

Referring now more particularly to the char- (Cl; 164-20) I I acters ofreference on the drawings, the machine comprises side frame beams Isupporting a bed plate! or the like, the beams'in turn being supported aconvenient height from the floor by legs 3. Cradles 4 forremovablysupporting'the. spindles 5 of rolls of shingle material 6 to becutproject forwardly "from and are mounted on said frame beams at theirends.

,Racks 'Iare mounted on and extend along the upper faces'of the sidebeams, said racks being engaged by gears 8 mounted on a common shaft 9'and having a' prfesser roller lIiconcentric therewith and extending'thefull distance between the gears. The shaft is'journaled: at its ends inbearing blocks II mounted for limited vertical movem'ent in carriages I1 depending outside the beams I. Said carriages have rollers I3 engagingthe beams I so that said carriagesarefsupportedand guided for horizontalmovement along the beams.

The bearing blocks are yleldably pulled down on the carriages bycompression springs disposed about the lower portions of bolts'IS whichare connected to said blocks at thesides and slidably dependthroughtheacljacent portions of thecarriages, f I

Another geanli is mounted outwardlyof and concentric 'with' one gear 8,.which-gear I6 is engaged by a pinion I1 mounted on the adjacent carrlagein horizontal alinement with the gear. pinion is connected to a crankhandle disposed, outwardly of said carriage so that upon rotationof thecrank the carriages and roller III will be moved lengthwise of the racksand at the. same time the roller. willbe turned. L Secure'don the plate!c'e'ntrallybi its ends is a' rectangular die frame I9 in which'ismounted a die indicated generally at 20 andwhich indicates upstandingcutters 2i defining the pattern or design of the shingleto be cut fromthe sheet material of the rolls. The die parts are removably locked inthe frame in a similar or the same manner as is employed in the printingindustry in locking the matrices, etc., and the set-ups in their frames.The pattern cut by the die is preferably my own design, being arrangedso that four single strips of standardwidth and length are cut at onetime from the roll of material without there being any waste of suchmaterial.

The bearing blocks II are arranged in supporting relation to the rollerIII and to the level of the cutter so that when the blocks are at theirI lowermost point of. the carriage the bottom of the roller Just clearsthe die cutter, as shown in Fig. 3 so that there is no possibility ofsaid cutter being dulled by contact with the roller.
